A kind of sound mixing control method and device of wince vehicle multimedia

Abstract

The invention discloses an audio mixing control method and apparatus for Wince vehicle-mounted multimedia. The audio mixing control method comprises: A, when supplications are started, generating corresponding process IDs, and when the already started applications need to play sound, creating corresponding audio streams; B, pairing the audio stream of each application and the corresponding process IDs for marking, and identifying the types of sounding applications according to the process IDs; and C, according to preset sound priorities, controlling the volume of an application whose priority is the highest to be highest, and closing or reducing the sound of an application whose priority is low. According to the invention, the volume of the application whose priority is the highest can be controlled to be highest according to the sound priorities, and the sound of the application whose priority is low can be reduced or closed, and such an automatic sound adjusting mode reduces the influence of other unnecessary sound, so that the problem can be solved that a user cannot listen clearly due to simultaneous playing of multiple sound at the same volume, manual operation by the user is unnecessary, the use of the user is greatly facilitated, and driving is not affected.

Description

technical field [0001] The invention relates to vehicle voice technology, in particular to a Wince vehicle multimedia sound mixing control method and device. Background technique [0002] The existing vehicle multimedia system can be compatible with multiple application programs at the same time, has various audio and video effects, and can realize functions such as navigation function, Bluetooth call, broadcasting or audio and video playback during use. In actual use, these functions may be used simultaneously. For example, when listening to the radio, the navigation function needs to broadcast the route direction by voice, or there is a phone call when the voice navigation is in progress. Because in the current Wince system, the navigation voice, Bluetooth incoming call prompt tone, broadcast or audio and video playback sounds are all set to the same type, the voice transmission channels of these sounds on the hardware are the same. When multiple sounds are played, the W...
